Abstract

Satellite communication holds a significant position in the modern communications domain, yet it is susceptible to interference and fading. Focusing on satellite communication systems, this paper delves into anti-interference and anti-fading technologies. It analyzes the causes of interference and fading and their impact on system performance, detailing spread spectrum communication and adaptive antenna techniques for interference resistance, as well as diversity reception and channel coding methods for fading resistance. Through an in-depth analysis of these technical principles, the paper illustrates how various technologies enhance the stability and reliability of satellite communication systems, providing theoretical and technical references to ensure efficient satellite communication operations.
